Revit 2016 to Autodesk Robot Structural Analysis Professional 2016 – New bi-directional load transfer

The Autodesk Structural Analysis Toolkit 2016 has been released for a few weeks now and I have been testing and using this during training and consultancy days and have discovered that the workflow now supports loads modelled in Robot and then transferred to Revit as well as a host of other documented features.

Revit to Robot Graphic

If the loading that is added via Robot is not supported in Revit, for example a thermal load, then you will see the following warnings when transferring the model.

Robot - Revit Warning List

When the transfer is made from Robot to Revit all the load combinations are also now transferred across. With this new functionality it is now much more realistic to add all the loads and load/code combinations in Robot and then transfer to Revit.

Revit Load Cases

The following enhancements are available in version 2016:

  • Gravity analysis: Apart from static analysis, you can perform gravity analysis. It is the analysis type which by deducing the flow paths of loads lets you determine how vertical loads are transmitted from the top to the foundation of the model.
  • Result Explorer: You can display and explore types of results for gravity analysis.
  • Perform analysis: You can perform a batch of analyses simultaneously. In the Analyze in Cloud dialog, you can specify a type and parameters for several analyses.
  • Website – 3D Structure Viewer: You can display results for static analysis and gravity analysis in 3D Structure Viewer. Moreover, you can display detailed results. Results for members and surfaces are presented in the Local Coordinate System (LCS).
  • Website – 3D Structure Viewer: On mobile devices, you can zoom in/out, pan, and rotate a model using gestures.
  • Website – project page: You can share an analysis with collaborators. Collaborators cannot edit results and cannot download them to the Revit project. They can view analysis results, view a report, and download the Robot model with and without results.
  • Website – dashboard: You can open the Autodesk® 360 Structural Analysis dashboard on the website clicking Analyze tab > Structural Analysis > Open Dashboard.
  • List of messages: You can toggle on and off the list of messages containing information about performed analyses by clicking Analyze tab > Structural Analysis > Messages.
  • Revit – Robot Integration: When updating a Revit model with changes in section sizes, the link checks compatibility between the section size from Robot and family types loaded to the Revit project. If it identifies a family type compatible with a Robot section, it updates the Revit model with it.
  • Revit – Robot Integration: You can specify which levels to transfer as story levels and which levels as structure axes to the Robot model.
  • Revit – Robot Integration: During the Revit – Robot link process, orientation of loads is transferred. Loads are presented in the Local Coordinate System or Global Coordinate System, depending on how they are defined in Revit.

Tips and Tricks – A Complex model in Autodesk Building Design Suite Ultimate

I thought I would share an interesting challenge I recently had for creating some complex geometry and being able to transfer this geometry both to Revit Structure and Autodesk Robot Structural Analysis Professional. I have used my own data just to verify and test the procedures required.

The software used within the Building Design Suite Ultimate package is:

  • Autodesk Inventor 2015
  • AutoCAD 2015
  • Autodesk Robot Structural Analysis Professional 2015
  • Autodesk Revit 2015

I modelled a Stadium within Autodesk Inventor and used the split command to create the various positions for the truss sections that I wanted to produce. The Inventor model is fully parametric and capable of change relatively quickly.

Autodesk Inventor - Stadium Concept

I then used the XEDGES command in AutoCAD to extract all the wireframe edges. The other option is to output the model to ACIS and then explode the geometry.

Stadium with Rational Geometry

This model was then taken into Autodesk Robot Structural Analysis by opening the dwg file. The lines are automatically converted to bars. I then assigned the relevant members and the model was ready to design.

Finally you can then create the Revit model from the Robot model! A lot of Autodesk software used here but if you have the Building Design Suite Ultimate then this could be a viable workflow.

Revit Structure – Using Load Take Down for Internal Dead Loads

Here is a very quick tip and trick for modelling dead loads from internal walls to your analysis programs. You will first need to ensure that you have the Load Take down tool added to Revit which can be download from Autodesk Exchange Apps

https://apps.exchange.autodesk.com/en

Once this is installed you will need to add your internal walls and make sure that these are structural and have an analytical model. In the image below I have created a filter to show these in Red.

You also need to add Boundary conditions for the slabs, walls and columns and set the fixity for these. You can then start the Load Take down tool from the Extensions Ribbon.

Revit Load Takedown - Linear Loads

Click the Structural Analysis command and then you can see the linear loads on either the entire structure or just the stories where the loads are applied. These linear loads can then be added to the Revit model (A manual process at the moment).

Line Loads added to Revit

The model can then be transferred to your Analysis application.

Enjoy,

Autodesk Project Storm

Project Storm for Autodesk Revit Structure is a technology preview that provides cloud-based structural analysis to structural engineers as a part of the BIM process. Project Storm enables structural engineers and designers to:

  • Perform static analysis from the cloud so as not to disrupt their workflow or hinder performance.
  • Simultaneously perform static analysis for various buildings models or parts of a project.
  • Calculate different variants of the same model for example using differing materials, at the same time.

Structural engineers and designers must perform calculations as a necessary part of the design process for any building structures project. Project Storm makes structural analysis more accessible allowing analysis to be performed from anywhere at any time by accessing computers in the cloud. Being able to perform analysis during the design process helps to streamline the Structural Engineers workflow.

Please note that you will need to install the latest service pack UR1 from Autodesk prior to installing Project Storm. See Link Below.

Once Project Storm is installed you will see the following additions to the Analysis ribbon within Revit Structure.

Simply submit your analysis and you will then be notified of results via a notification bubble. Click the Results button to show other results as desired.

Autodesk Project Storm can be downloaded from the following location.
